IMPROVEMENT IN CART Rinses Foe FIRE-ARMS.

Specification forming part of Letters Patent No.-l93,658, dated July 31,1377; application filed I January To all whom it may concern:

Be it known that I, BENJAMIN B. Boron, Kiss, of New York city, in theState of New York, temporarily residing at 27 Rue de Choiseul, Paris,France, have invented certain Improvements in Metallic Cartridges, ofwhich the following is a specification:

The improved cartridge is more particularly arms, but it may be usedwith success for larger cartridges required for my revolving cannon, andfor the Gatling and analogous machine-guns.

It is adapted for the Boxer primer, requires le to change... and avoidsthenecesandapplying rivets. awing represents what means of carrying outthe its condition with time,

I The accompanying dr I consider the best invention. i p Figure 1. is ageneral lon itudinal section through the entire cartridge, with theprimer in elevation. The succeeding figures reprecale. Rig. 2 is alongitudinal section through the primer, and Fig. 3 is a cross-sectionthrough the same.

Beferring to the drawing, A A is animular plate of stout sheet-iron. Aspacearound the central hole is made conical, or approximately so. Thesunk space thus provided should be enough to allow not only for the the.primer, but also for the thicknesspt the material of the internal cup,as will presently appear.

B is the body of the shell. It 'is preferably in the manner thecylindrical porbut this is not absolutely It may be produced in the formof 'now much approved for essential.

struction it has a slight shoulder at b, and ged inward, as indicated by0 O is an external the lower outer corner of the external cup or cup,strengthening generally known as the Boxer. It is the form made byGoupeir, of Paris, its exterior being a short tube flanged inward at thefront end, and outward at the back end, and containing in-its interior apercussion-cap and a suitable anvil.

D D D is a piece which performs the important functions of an internalcup, at lining around the central hole, which fits tightly to the primerE, and a flanged or turned-out pertion in rear of the central hole. Itgives unityto the base. The part D corresponds to an ordinary internalcup, the part D is a lining for thecentral--hcle, and----the part D aflange in rear thereof.

The parts, with the exception of the primer, being applied. together, asuitably formed header is brought into pl end D and cause it to fir theparts together. prepared being forced 'chine,*the cartridge is ready forcharging.

My improvement is particularly adapted for military use with small-arms;but it may be used in breech-loaders of all ordinary patterns, and forall ordinary purposes. The front of the cartridge may be united withaball, or

ot for sporting, or may be mly clinch and rivet The primer previouslyhome by a suitable maojectile or collection of pro- Witnesses WM. 0.DEY,
